Assign a baseline in Microsoft 365 Lighthouse

By default, Microsoft 365 Lighthouse assigns the default baseline to all tenants. You can create and assign a baseline to accommodate varying customer requirements.


Some features get rolled out at different speeds to our customers. If you aren't seeing a feature yet, you should see it soon.

To see which new features are currently available in your partner tenant, go to the Home page of Microsoft 365 Lighthouse, and then either select the What's new link in the upper-right corner of the page or select What's new on the What's new & learning resources card.

Before you begin

Make sure you and your customer tenants meet the requirements listed in Requirements for Microsoft 365 Lighthouse.

Additionally, each partner tenant user must be a Microsoft 365 Lighthouse admin.

Assign a baseline to a tenant

  1. In the left navigation pane in Lighthouse, select Tenants.
  2. Select a tenant to which you want to assign a new baseline.
  3. Select Assign baseline.
  4. Select the baseline you want to assign to the selected tenants.


Baselines don't include tenant-specific attributes, and the assignment of a new baseline will overwrite any pre-existing customization to the configuration of a tenant's deployment plan, such as deployment task dismissals, user and user group exclusions, and deployment statuses of manual deployment tasks. These values will need to be re-entered for each tenant, as needed.

Next steps

Once the baseline is assigned, Lighthouse queries the assigned tenants to detect and report their deployment status. Review the deployment plan to determine the next steps in the deployment process.
